Chris P: hi donyboy I have a question, what fuel oil mixture do you recommend for most applications. In the old days 16:1 was common, now it almost always 50:1 would that leaner mix ration cause shorter engine life and lower compression. Do you recommend a richer mix? thanks
Brandon Byard: I have a craftsman weed eater that looks like that one it has good compression and good spark but it won't start what should I do
donyboy73: did u see my repair vids?
donyboy73: @tehkingzorzvlog check out my carb repair videos for these trimmers
tehkingzorzvlog: i have a question about these trimmer it runs but it only runs for like a minute and then bogges down and dies??? asap
donyboy73: @outlaw44mag could be too low on compression
outdoorsman310: i have that weedeater... its not good
niper99: @IW5Industries has the spark plug been changed? if not l would do that first. if it still does it l would check and make sure the exhaust isn't pluged with carbon, if thats checks out good then l would check for a fuel pump pulse from the crank case. (this all is assuming the carb is clean!! make sure its not clogged behind the little screen in the carb)
niper99: well l got a homelite in the shop the other day and it was only reading 65 psi, it came in as a no start. l put a carb kit and it started right up and runs amazingly well and with decent power to. but l would agree with donny that in 90% of the cases these machines require at least 90-100 psi to perform well and in most case even start. and what starts to happen with low compression is it causes blow by which these motors need negative pressure to run the fuel pump.
Pgxi: @donyboy73 .....thanks dony
30GB: @PGXI in the cylinder
30GB: @PGXI put wd40 in there like a cup for a day then start her up and there should be no more smoking
Mrtocoolforyou12: i got a echo trimmer srm 230 and srm 280 that has 135 psi for the srm 230 and 155 psi for srm 280
donyboy73: @PGXI a leak down test, crank it over very slowly and you will feel it a bit better. also if it burns oil you may need rings.
Pgxi: hey dony...? i have a 9hp tecumseh snowking....is there a trick to testing them it has that compression release on the valves...
i want to check it before i start to repair it..to see if it`s worth rebuild...thanks dony
BriggsMower: iv got a ryobi whipper snipper its only got 62-65 psi of compression
CoRRisioN: @Joeyad4 what are u 6 grow the freak up and stop talkin crap on dony's channel
Garrett Jdbe: i just tested the compression on my simplicity with a Vanguard v-twin the valves need to be adjusted on the right cylinder
satan31337: @IW5Industries i had the same issue, put a new carb kit in to.. ran awsome.. oh and new fuel lines
th19940305: my lowest compression ive got on a running weedeater is about 85 psi and highest proobably 140 psi
