Very useful information shared. Thanks.
I also got my 2500 Watts Honda clone chinese generator rebuilt which worked successfuly for last 3 years. Got all rings, piston, primary / secondary oil seals, carburetor, plugs etc changed. After all above, now I am facing a problem that probably due to a new carb, it doesnt start without applying choke while on petrol. As far as sui gas is concerned it doesnt start at all. However, after staring on petrol, it is converted to gas and it works fine.
Before the overhaul, with worn out carburetor, it used to start without choke and also on sui gas. I also have home made ATS which was working fine before but now due to bad starting it is of no use.
I liked the idea of using a central lock motor for choke, but on natural gas therer shouldnt be any issue of choke? Any suggestion for quick starting on gas??
