OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Trimmers and Brushcutters Two Stroke Trimmers & Brushcutters tanaka 220 tbc

hi Bruce
Me again..
I sold the tbc 4200
and now have a 220 that I'm tryinh yto fix

i have put 2new rings on the piston
new fuel hoses, (not original hoses)
new fuel filter, and air filter
have set the idle to where the head stops spinning.
not the easiest to start now before it was a dream. when it goes it goes ok sometimes then other times it bogs down, then sometimes when its idling the revs fluctuate a little then dies

would be great to have your advice
thanks Bruce...

briggsboy,

Sounds like you need to replace the carby diaphrams.

When you have it running, if you shake it do the rev's fluctuate? :p

If so it is carby.

What was the cylinder like?

hi Bruce

The cylinder is in great condition, the piston had black on it but it came off easy with a litle steel wool, the only reason i replaced the rings was coz i broke one as i tried to put it back into the cylinder head .... ouch....

thanks bruce

sorry

yes the revs fluctuate before it dies

briggsboy,

Please answer questions that I had asked. Your reply doesn't answer specific questions.

I need the answers to my question in order to give correct information regarding your problem.

thought i had answered your questions

yes it fluctuates

briggsboy,

I assum then what you are saying that the rev's fluctuates when you move the machine (like shake it).

1.What type of fuel filter (brand) did you use?

2.When you put the fuel line in and the filter is on it, does it reach the furthest point of the tank?

3.When you put fuel in the tank and cap on does fuel come out of the fuel line when it is not connected to the carby?(you will have to clamp the line that does not have the fuel filter on it)

Just one silly question:
Have you put the fuel line on the carby correctly ie on the inlet (fuel filter one) and not on the outlet?

hi Bruce

I did the test re clamping the line with no filter and the fuel flowed out of the line that goes to the carby... with or with out filter
.
The filter i use is a metal type that i got from a hobby shop used for small petrol racing cars..

Re how the lines are conected i had them done each way and one way i had it when i pushed the primer once the petrol came out at poured right out of the carby..flooded i guess the word is..

the other way i dont see it going in but it does the job in that fuel is there also..

regards Frank

ps..hows the parts for the Mccullock chasinsaw going ?

hi just wondering when you are going to get back to me ?

briggsboy,

I can only get second hand parts for the chainsaw. I will send you costing this week.

As to the tanaka, what sort of petrol cap is on it?

hi
its a tanaka fuel cap original.
I've ordered the carby filter kit
and putting on the original fuel filter
see how that goes

Frank
ps..
will wait for your parts quote thanks

briggsboy,

You did not answer one of my questions s o I will ask it one more time.

Did you replace the carby diaphrams?

no i did not replace the diaphrams as yet they are orded and will put them on asap when i get them..

I will follow up when they arrive ..thanks..

i incorrectly typed (carby filter kit) when i should have typed carby diaphram kit, that is the misunderstanding on my part re you thinking i didnt answer your question.. sorry

regards Frank

briggsboy,

Let me know once you have replaced the diaphrams if it sorts out your problem.

hi Bruce

I changed the diaphram hoses ect nothing was left out
being a good machine i surcummed to having to give it to a pro.. hmmmm
after seeing it he rang me and told me the head (inside chrome plated) was coming of and was no good only option to throw it away ...I found it hard to believe because it worked great. i put new rings in and you know the rest..
do you have an old head tanaka 220 around ?? i know that answer sadly....
any other ideas ...how much is a head worth

regards
a sad little briggsboy

briggs boy,

Can you take a picture of the inside of the cylinder as I have never come accross the chrome pealing off the cylinder in 30 years.

If you were talking about a Ryobi yes I would understand.

hi
sure i pick it up today (Wednesday)
and i will take the pick..
might i ad i find the whole thing odd

regards Frank
