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

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

Tim R: I'll do one on my brand new weedeater today, i'll post what i get later.

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.

donyboy73: @tehkingzorzvlog check out my carb repair videos for these trimmers

donyboy73: @outlaw44mag could be too low on compression

Tim R: My new ft20c weedeater was 120psi too, amazing those little engines has that much psi!

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

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.

satan31337: @IW5Industries i had the same issue, put a new carb kit in to.. ran awsome.. oh and new fuel lines

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)

Rarrin9378: I got to do this to my Ryobi trimmer it is so easy to pull the cord it basically flies all over the place if you pull it to fast.

MO3MINI: im buying a compression tester, i just have to find out how low the compression is on my running worn briggs, there little resistants but it starts, runs and smokes like hell :) will you be testing any 4 stroke engines? and could you test a very worn engine? that would be great :)

BriggsMower: iv got a ryobi whipper snipper its only got 62-65 psi of compression

lawnman579: a quick and simple way to test compression is to take the spark plug out and put your finger over the end of the hole if you hear a loud hissing and your finger is blow up a littel its ok to buy

outdoorsman310: i have that weedeater... its not good

30GB: @PGXI in the cylinder

th19940305: my lowest compression ive got on a running weedeater is about 85 psi and highest proobably 140 psi

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

CoRRisioN: @Joeyad4 what are u 6 grow the freak up and stop talkin crap on dony's channel

ranger220022: Correct me if im wrong,but a easier way to check to see if you got good compression is when you pull the cord up a bit and you get the tension,u got compression.

lawnman579: hey tehkingzorzvlog your proplem is the diaphrame in your carborator its not hard to fix the kit cost about 7 or 8 buck cheaper than buying a new one i will make a video on this later

donyboy73: did u see my repair vids?

30GB: @PGXI put wd40 in there like a cup for a day then start her up and there should be no more smoking

PGXI: @donyboy73 .....thanks dony

lawnman579: yes donnyboy73 i have seen your repiar videos the one on the pulsa prime carborator was very helpful ive now got my mower running great ive also changed my user name

donyboy73: @1972FordF150 sure man

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

1972FordF150: I have a video of me testing the compression on my weedwacker. Want me to post a video response ?

donyboy73: @CARRICK6423 maybe in the future, some of those engines i can't do a comp test with a regular tester because they have a decompressor built into the camshaft
