Re: 87 15h rude starting problem
Warren, a few further thoughts ...<br /><br />Analyse what you’ve got:<br /><br />1. The motor runs fine once you get it going. That suggests the timing’s OK or it wouldn’t ever <br />run well.<br /><br />2. The fact that it runs as you describe suggests (although not conclusively) that the electrics also work, because a usable spark is produced, whether the engines’s cold or hot.<br /><br />3. That leaves fuel as the most likely culprit. So Check all aspects of the fuel delivery. Start with <br />the tank, then the bulb, then the lines to the pump (including filter if you’ve fitted one), then check the pump operation, then the carb. <br /><br />Use this sequence:<br /><br />Disconnect fuel-line from engine at quick-connector, push a paper-clip in the end of the line (to keep the line valve open), and prime with bulb. Fuel coming out OK? Reconnect. No fuel? The problem’s in the line or bulb from tank to engine.<br /><br />Then pull the line off just before the pump and squeeze bulb again. Fuel OK? Reconnect line and move on.<br /><br />Disconnect line at carburettor, and turn engine over (pull-start or electric - makes no difference). Fuel should pour out. If it does, the carburettor needs work. If it doesn’t, the pump needs work.<br /><br />Check for leaks at every joint by smothering each joint with grease, then run engine if you can, and remove the grease joint by joint. If the motor then runs badly (or stops) you’ve found a leak.<br /><br />If none of the above makes any difference, either the components (especially the carb) are still not <br />clean and clear enough, or we’re back to the electrics.<br /><br />Hope this helps.<br /><br />Ciao
