Jimk submitted this idea :
Carbs nearly new albeit an eBay Chinese clone of the Honda.. come to think of it it didn't run any better when I put it on, & I kept the old carb........ Fuel restriction - blocked jet, poor fuel flow to carb blocked filter, blocked air vent to tank. Why did you fit a new carb.? |

Jimk used his keyboard to write :
Don't think there is a filter unless it's hidden? Presumably as it will run with a little choke fuel is getting there ok? Normally there will be some sort of filter, even if only a mesh strainer. Pulling the choke, will increase the vacuum to increase the flow of fuel, limit the air going in - so it is not proof that the fuel flow is OK. |

Jimk explained on 17/08/2020 :
Topped up a month ago, but that will have been in the can for a few months... I have heard of this many times - the old fuel problem, but I have never suffered it despite having engines and fuel stood for years. A problem I have come across several times, is carbs gummed up by fuel residues. |

I have heard of a solution which poured into the fuel tank, helps preserve the fuel - I don't know if it helps prevent the carb becoming gummed up. |

A problem I have come across several times, is carbs gummed up by fuel residues. is there a "redex" type solution to that? If its a dirt obstructed jet, one fix I found long ago is... With no air filter in place, rev the engine hard and whilst the engine is at peak revs, slap the palm of your hand over the carbs air intake. That applies a lot of vacuum to the carbs jets, which might suck any dirt through to burn off in the engine. |
