Ok a few weeks ago I bought a snowblower. Its an old Honda HS35 3.5HP 4 stroke. Its a single stage unit with only choke control (no speed control, runs only at full choke or full speed which is like 3000rpm)
First day I tried out the blower it ran fine, untill about 3-4 min into it, it started to die and woulnd't keep speed anymore (speed was surging and oscillating from idle to full speed, but wouldnt keep full speed anymore)
I figured someone was up with the carb so I took it out and let it soak for a week and put it all back together. I checked the fuel filter and its no clogged at all. I ran it the other day and it ran better, staying full speed untill I noticed the fuel bowl was loose and gas was leaking out, and then it started surging again. Since then its been in the garage because I have to tighten the fuel bowl better.
Im asking this because im wondering if a clogged main jet could be causing this or if you think my latest problem is more related to the fuel bowl issue and it should be fine? I want to make sure its running good tonight cause were supposed to have a storm overnight.
Just to recap things done so far:
-Carb soaked and cleaned (forgot to take a small wire and poke out the main jet though)
-Checked fuel filter (ok, fuel is supplied to the carb)
-Oil has been changed and is topped up
-All old gas has been drained from tank and fresh new gas with carb cleaner additive aswell
Pretty much it should be running ok. Could it also be a bad gascap? I did unscrew it when it was running but it didn't make much of a diff, although I only had the cap off for about 10 sec than put it back on.
Any tips are appreciated thanks.
