This video deals with replacing the optical coupler in a Vox Cambridge 30 guitar amp. The component can be sourced from Thonk in the UK. Not too expensive and a quick service. Make sure you get the component the right way round. When you remove the back cover, the led section of the component is on the right hand side legs. The positive leg goes closest to the potentiometer above it. Took me around an hour total to replace and rebuild. Was disappointed when I tried it out, but then adjusted the potentiometers as per the video and it's like a different amp. This is guidance only. I do not accept any responsibility for injury, damage or death by fiddling with your amplifier. I'm really pleased with the improvement this repair has made. I'm definitely keeping this amp now. Cheers for watching.

Bought as a project. Piston seized in barrel. Cooling non existent. Throttle cable broken. Stripped motor completely. Barrel totally clogged with years of salt/sand/mud etc. Both water inlet ports had to be drilled out! Pump inspected and cleaned. Leg oil replaced. No signs of water ingress. Carburettor stripped and cleaned. Fuel tank cleaned. Fuel tap stripped, cleaned and rebuilt. Steering tensioner repaired. Throttle tensioner repaired. Shear pin replaced. She now starts easily, runs well and cools better than any DT I've ever owned. 4 hours well spent :) Thanks for watching.

Bought in bits as a non runner. Gearbox driveshaft bent Gear selector bent and fitted wrong Carburettor blocked Thermostat jammed Tell tale passage blocked I've spent about 7 hours on it and it's now running like a beauty. The four stroke twin and rubber mounted engine makes it very smooth indeed. It's getting on a little now (2003), but it's a typical Honda.... Built well and reliable BUT BLOODY HEAVY! (34kg) I'm chuffed with my efforts.

£60 of steel, a ram we had in the shed and some time spent cutting, drilling, grinding & welding and we're good to go. Just gotta fit a spool valve so it can become a one-man operation. At 200 bar, this splitter is capable of 6 tonnes push force. We don't have a gauge at the moment, but we're guessing the tractor is putting out about 150 bar max, which equates to approx 4 tonnes. Splitting a treat. Amazingly powerful. :)

Plastic fuel tap cups in older Suzuki DT3.5 Outboards are naff... The threads wear out and I believe modern fuels don't agree with the material. This tap mentioned in the video has a cup which will screw straight into a Suzuki tap... complete with new seal! Its a cheap way to revive the original tap. Seller is bgood2010 Current price is £1.99 plus shipping Hope this helps someone! Remember folks, you fiddle at your own risk. I take no responsibility for your actions. Jon

The noise at the start is my Dad blowing his nose - Honest! This engine would start with choke and anything over half throttle. Roll off the throttle once the choke was off and it'd die instantly. There is a tiny pilot jet beneath a small brass plug on the carb. This jet can block really easily and is a press fit, so cannot be removed. The pilot jet feeds into a drilling that connects to 3 tiny holes in the bore of the carb. Take a close look - you'll spot them. The jet and these three holes MUST be clear in order for the engine to idle. The carb picks up it's pilot fuel supply from BEHIND the main jet. Take the main jet out and GENTLY push/bend the atomiser tube over to one side. There is a hole around 2mm diameter hidden here. The fuel then travels up the smaller tube next to the main tube in which the atomiser sits and then makes its way over to the pilot jet (beneath the brass plug) and then finally through the small holes in the bore of the carb and into the engine. The pilot jet is definitely the Achilles heel of this design of carb. If the engine has stood for a while, then my bet is on this jet if you have idling problems. If you need help with your DT3.5, then drop me a line and i'll do my best to help you out. I have a Suzuki manual and I've had quite a bit of experience with this model of outboard. Thanks for watching.

This is nacho, my ratty QT50 I picked up for £60. I fitted a 15mm dellorto clone carb to see if it would work.... It started first kick. The main jet is marked as a 58, but using my micro drills as a guide it looks more like a 65-70. I've literally done nothing to the bike. I found him on a farm in the Norfolk countryside. I have plans.... Watch this space ;)

A quick comparison of the response of two different tuners... A cheap, e bay purchase and a better quality version £3.99 vs £13.95 Buy cheap, buy twice definitely applies here

Bought as a project. Handle and mounting bracket cracked. Must've been dropped at some point in its life. One cover clip broken too. Ran great apart from cooling... Had handle bracket tig welded back on. Stripped it down totally. Rebuilt carefully with new prop shaft cover tube (22mm plumbing pipe) and plenty of sealant. Now pumps well and starts first pull hot or cold. Cooling seems marginal on these little motors. At mid/high rpm it keeps cool, but at tickover, the tell tale gets warm quite quickly. Anyone else notice this? The impeller is behind the prop, so is running slower than a more conventional pump assembly which is normally housed in the leg and powered by the engine's prop shaft (pre reduction gearing so greater rpms at the impeller) Well, it's another outboard added to the collection. Beats rowing anyday! Cheers!

I got given this when I went to collect two Johnson Seahorses from a chap. No idea of age It's direct drive Air cooled 4hp Power out sockets External tank 25:1 mix 2 blade prop I love it! It's lightweight, with no water pump to fanny about with. It's amazingly quiet too. Much, much quieter than a seagull. It's simple, pokey and portable. Seriously thinking about using it on the broads this winter when we're after the pike. Another one joins the collection :)

Forty Plus. GFP1042FF6 - June 1976 Oddly mated to a clutched leg. Villiers carb rather than Bing (G in code) 3 blade weedless prop - nice! Started 2nd pull after a lengthy rest in the shed (15 years?) Seemed to run quite happily on 25:1 mix...... hmmm. Not checked needle yet. Exhaust relief holes have been opened out slightly - a wee bit noisy. V happy indeed.
