Re: Starting Problems

I assume you have the "new" bellows without any drain system? Innocenti dropped the drainage system round about 1967 to save costs, but the "new" system can allow fuel to gather within the bellows as Mick says above. I tend to put a very small hole in the lowest point of the bellows (1 or 2 mm) to a...

Re: TV175 S3 won't start......

yes- quick relap.

Was a bit odd as it obviously went further advanced initially causing the hard Kick Back. Then it must have gone retarded causing the backfire. The F/W was turning but in the wrong position.

Re: Houston ....we have a problem ...

Are you possibly trying to fix a "150" inlet to a "200" inlet manifold stud spacing? The two inlets have different stud spacing dependant on original cc- the "150" type studs are closer together than "200" type. not sure what you are talking about now ................ You cannot fit a small block i...

Re: Houston ....we have a problem ...

"I have now had the opportunity to measure all the dimensions of the 3x engines that I have and have finally worked out what the problem is. It is the 200cc barrel or more accurately it is the inaccuracy of the bored and tapped holes for the inlet manifold which on my barrel are about 5mm closer to ...

Re: Houston ....we have a problem ...

The pictures not brilliant but that appears to be a normal larger engine mount- there appears to be the remnants of the usual white paint thereon. Innocenti produced two engine mounting systems- all S3 LI models and anything before used the short bar with the engine mount totally enclosed within the...

Re: Houston ....we have a problem ...

the larger blocks would have been fitted to your bike originaly. and allow the fittng of the usual carbs i.e 18/20/22 dellorto. the problem will be with the manifold if not original or more likely the barrel if it is one of those linered alloy indian jobs as they are known to have the inlet surface...

Re: TV175 S3 won't start......

thinking about it- when it started "not starting", it was kicking back really strongly on the K/S- something its never done before. That in my opinion suggests well over advanced timing. Its not kicked back since, but now occasionally backfires badly, which suggests well retarded. The indications ar...

Re: TV175 S3 won't start......

I've given it a go Martin but with no luck- I am coming round to the fact that its timing related i.e. the flywheel has slipped if the key has gone. Unusual though as it happened after I used the gunk but may be as Mick says, it could be coincidence.
