Meaning I can have 34mm venturi and 30 mm mixer? Would it have any affect when running on petrol? And my other question was if carb is not properly jetted for my engine (for petrol) if i fit proper mixer plates, will it run good lpg (I am talking about simple but efficient Solex PHH sidedrafts)? -- ___ ____ /__/ / \ ** Registrovani korisnik Linuksa #291606 ** / / \/ /\ \ ** Registered Linux user #291606 ** /__/\____/--\__\ ** http://counter.li.org/ **

If the petrol carb is much smaller, it might not work so well. I think that formula is right: lessee, that gives a range of about 30-35mm diameter, which is probably somewhere close. > >And my other question was if carb is not properly jetted for my engine >(for petrol) if i fit proper mixer plates, will it run good lpg (I am >talking about simple but efficient Solex PHH sidedrafts)? If the petrol carb is really off, then you might get better results on LPG. Mostly, engines seem to run smoother but not quite so much power. -- Austin Shackles. www.ddol-las.net my opinions are just that Too Busy: Your mind is like a motorway.
