Carb Rebuild

[Guest lotusPaul]

Considering the above I too would check valve lash. Agreed that compression is low, but as they're all same it could be you have a low compression engine.

Another free check could be to make sure exhaust is not blocked/ restricted.

 

I would still want to check plug colour and ignition timing.

will do plug photos tonight forgot socket and recheck timing forgot light but realised not to bad upto 60 mph just on from that

[Guest lotusPaul]

So ok up to 60mph but not above. Does it rev under no load?

[keith kelly]

Is this the engine you had off me? Certainatly had better compression when it was in my zero a definitely went over 69!

[jaimo]

Revs fine when stood under no load just runs out of power and drop in 5th at 70 forget it could it be fuel pump and no keith its the 1800 stil got to finish rebuild on that as u know new houses and kids and work get in way

You say you got vac dizzy. Take off vac pipe and try a run. If its the same then I think you may have your cause.

 

I'm trying to eliminate and isolate your problem here so stick with it

 

Also with vac pipe off give it a good suck while still on dizzy end.what does that do?

[jaimo]

Will try paul and report do i need to block vac

Also the carb has an enrichnent device connected to a seperate vac pipe standard on some weber 32/36 what is this

I mean to take of the vac pipe from carb and keep it connected to dizzy. Give it a suck and feel if you get resistance or movement within dizzy. To be honest a timing light will tell you if its working too. I put a link up above, is this your carb?

[jaimo]

Yeah thats it but got a unit that is fitted on few of these carbs its blanked casting on most but mine acuually uses it i will try get pic up wen home google weber 32/36 enrichment dhaphram
