Afternoon!
My 914 has a 1.7L engine(original) and I am running a pair of 36IDF carbs. I have rebuilt them personally, had another relatively local 914 specialist rebuild them and I am still not entirely happy with the way they perform.... Transition and coming on to throttle up to when the main jets come on seems to be the issue. Is there a rebuilder/cleaner that everyone on here recommends? I figure some sort of ultra sonic blasting to clean out the ports/chambers that I am not able to get to would be the best. Any insight? Possibly also rejetting suggestions might be good as well. Thanks, Casey |

You're sure that it is the carbs? Two people, yourself included have rebuilt them and you're sure the jetting is right and there is still a problem? You don't have a vacuum leak at the bases or a balance problem?
Rule out another problem before you spend bigger money on the same solution. |

You don't have a vacuum leak at the bases or a balance problem? Rule out another problem before you spend bigger money on the same solution. (IMG:style_emoticons/default/agree.gif) With Rob and Kevin. As I sent you in the PM, you probably want to blame the carbs last at this point. It often is them, but it could very well be something simpler and cheaper. I.e. adjust the valves, verify timing and ditch the crappy 009 distributor if thats whats you're using. Also, ensure you have a quality fuel pump and regulator and adequate (3.5 PSI) fuel pressure. THEN you can fuch with the carbs. After you follow Kev's advice and read Tomlinson's stuff, of couse (IMG:style_emoticons/default/smile.gif) Welcome to the madness my friend. |
