Are you sure you timed it correctly? You used the 2 dots and not the TDC line for static timing? Is it 180 degrees out ( but then the static timing wouldnt work anyway, but....). Its rare for them to come loose, but is the timing cup tight? Concur, stock Blasts do tend to backfire because they are set very lean. If you've got the 45/170 set up you're fine and backfiring should not be a regular problem. If you're getting spark at the plug, I'd certainly try starting fluid. And if you've got spark at the plug, then its unlikely any safety switches are acting up (on start up). If you disconnected the headlight and your bike is cranking over fine, I dont see any reason to buy a new battery. You might consider a compression test. FWIW: I run Sportster carbs and I dont having any issues with fuel delivery ?!? |

@ Gearheaderiko: It is the fuel inlet fitting on the carb that is stuck in an odd position, pointing upwards. If it every cools down here in FL, I might actually feel up to working on it...lol. |

@Gearheaderiko: I've tried using starter fluid and it comes close to turning over and starting. However, it doesn't quite catch. I'm getting close to just taking the bike in to Saint Paul HD. No local shops will work on the bike. How do I do the Compression Test? |

Fuel inlet position should matter as its still lower than the fuel tank. It doesnt matter on mine. If its not starting with starting fluid, thats a bad sign. To check compression you first buy/borrow a compression tester gauge. Usually under $20. Remove the fuel tank (just lay it carefully to the side, you dont have to pull the hose). Remove the spark plug and insert compression tester in the plug hole (2 types: hold in or screw in). Then crank the engine over a few times holding the throttle wide open. Watch the gauge. It should end up reading 120-170 psi. You might want to google "checking compression" or "Compression test" that might give a better explanation than I gave. |

Ok so I have a 2001 buell blast that I bought a few months ago. It was left in my friends garage for 6 weeks and won't start now. I have replaced the gas, the plug, the spark wire and changed the oil and filter. If I spray starter fluid into the carb it will start if I give it a lot of gas and keep the rpms up but then it will stall out. Can anyone help me? |

A common occurrence with bikes that sit is the slow/pilot jet will clog. A new #45 jet is a better bet than trying to clean the old one (but it can be done). New 45 jets are readily available at the Harley dealer. But PLEASE please PLEASE don't take the carb apart to "give it a good cleaning". It doesn't need it and you'll very likely create new problems. Just replace the jet. That's my first guess on an engine that only seems to run at high rpms and seems gas starved at idle. covering the carb inlet can also create a rich situation for starting! Also consider the carb boot "das boot"! They are seemingly the number one offender for problems so do look closely at it. |
