Things to solve a cold start issue?

[LN106G]

Ok lets see. First things first. The TS did not mention if the cold start happened BEFORE or AFTER the carb overhaul. She did not also mention if the the repair kit of the carb she used to replace the old one was an exact replica. What Im trying to drive at is that if you let the mechanic do the purchasing, chances are, they will just get the one (even if it is not the exact replica) that is available in the nearby auto supply & do the "remedyo method" back in their talyer just to make things done & save time. This will make the reliability of their work questionable. I am asking this as I've grown up with carb -equipped engines and by experience, a little mismatch of the replacement repair kit from the OEM kit (even with a mismatch of 1or 2 holes in the gasket, the setting of the fuel float) will give your engine hardstarting. Good thing if the mechanic who did your carb overhaul kept your old repair kit for future reference....

Cold start already occurs even before the carb was overhauled, mas malala pa dati dahil nag-stall ang car after 3mins of idling. Actually, the carb was overhauled twice. The 1st mechanic who did the overhauling job, nagpabili ng OEM carb repair kit na puro o-rings lang which costs 1,6k. But after that hinde pa rin nawala ang cold start at stalling issue. So after a month, we decided to bring it in kamuning carb experts na, and dun po namin nalaman na mali pala ang carb repair kit na pinabili nung unang nag-overhaul, sa scenario nung car na nag-istall dapat daw ay yung complete carb repair kit ang pinabili na may kasama nang plunger, jets, mga turnilyo at o-rings, etc...and this is much cheaper dahil 1k lang po itong complete set. And after it was overhauled correctly, nawala na po ang stalling issue.

Twice po kami nagpalit ng repair kit...OEM and the replacement one but has the complete set. Wala po kasing OEM na repair kit ang honda na may kasama plunger, jets, etc puro o-rings lang.

That's good additional info you gave. From that info, I suggest you check the fuel pump if it is still up to the task. Check also if the engine timing is "dead-on" target. Adjust valve clearance as necessary. I highly suggest you look for a highly competent mechanic who understands carb - equipped engines...

Cheers!

Actually sir, ganito po ang nangyayari every morning. At first start, mabubuhay po ang engine for 1 sec at tipong magbo-vrooom lang and after that mag-ooff na uli. Then the succeeding clicks while pumping the gas pedal ay hard starting na at aabutin na until 4 tries before the engine would finally starts.

Bring it to a highly competent mechanic for "fine-tuning" the things necessary for a complete tune-up. Make sure also there are no vacuum leaks with the hoses of your carburetor.. A knowledgeable & experienced "old-school" mechanic may help you...

Actually, thats one of our problem din sir, wala pa pong mahanap na right mechanic in our area to handle the situation. Hopefully, yung mga gurus po natin dito from cavite ay may marecommend na trusted and tested honda mechanic around bacoor or imus.

Maybe you can check out honda club philippines. Im sure they can recommend a good mechanic in your locale. It is very difficult to diagnose a car if you dont see it "in the flesh" even with good inputs here....

Maybe it is worth to invest more and have the repairs done in the casa.

have you check the carb choke machanism? why not check it manually? takpan mo ng kamay mo ang carb while starting it. pag mag start agad, choke ang problema mo. just give it a try.

2 hose nya,yung una galing sa gas tank,yung isa pupunta sa carb,Ito ang ang tanggalin mo,then,pitik pitik sa ignition( starter) pag walang lumabas na gas sa fuel pump,that's it,palitan mo na.hth

Sir, we already tested our fuel pump. Exactly as you stated, inalis namin yung rubber hose connecting to the carb and pump, then start the engine and fortunately sumirit po ang gasoline from the pump, dami nga pong natapon...so its safe to say theres no problem with our pump, right?
